Handling and Storage

In order to prevent polymerization, methacrylic acid must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. Methacrylic acid must be stored between 18 and 35 °C, preferably between 20 and 25 °C. To prevent freezing, the temperature of methacrylic acid should never drop below 18 °C. Improper thawing can result in violent polymerization.
